Would a low ejection fraction of the heart be detected by a holter monitor?

[joshred4]

I am 23 years old (male), and in fairly good health (6'0/180 lbs), and back in October I fainted after feeling as though my heart rate dropped considerably (felt like long pauses between beats). I had gotten up out of bed to use the restroom, after finishing in the restroom, I fainted. I regained consciousness instantly after fainting, and I haven't fainted since. Needless to say, this fainting episode sent me into an anxious frenzy. I had blood work and an EKG done in December (both normal), and I wore a holter monitor in January (also came back normal, but I posted the results below).

In spite of these results, I still happen to get odd symptoms such as chest pain off and on, as well as pain in both arms (off and on) and jaw pain (off and on). I also constantly feel light-headed, and many times I also feel short of breath. After exercise, the light headedness is much worse, but I'm not sure if this is just me working too hard and being out of shape.

I know all these symptoms could easily be anxiety (for example, from clenching my jaw too much), and if it weren't for the fainting episode back in October, I'm not sure that I would be concerned at all. With that said, I am still having a ton of anxiety about this, and I was wondering if something like low ejection fraction would be detectable on a holter or not. I am at the point where I may go back into the doc to get further tests, but I don't want to be spending additional money if I don't have to.

HOLTER RESULTS (JANUARY):

DIARY ENTRIES OF "POUNDING JAW PAIN, CHEST PAIN AND BURNING, LIGHTHEADEDNESS
AND PALPITATIONS" DOES NOT CORRELATE TO ANY SIGNIFICANT FINDINGS.
SINUS RHYTHM WITH AN AVERAGE HEART RATE OF 69 BPM.
245 RUNS OF SINUS BRADYCARDIA OCCURRING DURING NOCTURNAL HOURS WITH A LOW
HEART RATE OF 35 BPM AT 02:20 ON DAY TWO.
72 RUNS OF SINUS TACHYCARDIA WITH A MAX HEART RATE OF 152 BPM AT 18:13 ON DAY
ONE.
THREE VE SINGLES (<1%).
ONE SVE SINGLE.
RARE SINUS ARRHYTHMIA  OCCURRING DURING NOCTURNAL HOURS.
ONE JUNCTIONAL ESCAPE BEAT NOTED AT 19:07 ON DAY ONE.

No, holters tell us literally nothing about Ejection Fraction.

Echocardiograms measure ef.

Invasive angiography, ct scans and mris also measure ef. EF is taken by actually looking at the heart, in picture form and measuring it in some way.

I also experience heart palpitations.

Additionally, I had an echocardiogram in 2014, and that came back normal. Is it possible to randomly develop low EF a couple of years later?

It is possible to develop low EF in the setting of some sort of profound new disease process.

Some signs of this however would apprear on your regular EKG.

Further, you would experience other symptoms. These diseases I speak of include things like kidney or liver failure, genetic abnormalities, cancer etc. Few of which present without other symptoms that are not associated with cardiology.

A repeat echo however can never harm anyone physically speaking. Theres always the chance to pick up something new, with little to no risk to your health. Financially speaking this is another issue, all I can say is if you had an infinite supply of money and/or echos were free you'd have literally nothing to lose.

I am not qualified to suggest you accept or forgo any testing, especially on the basis of internet posts such as these. Unfortunately you are the only one who can make that call.
